[2025] 7 Best Blob Video Downloader Online Tools That No Software

By Rowan Ellis · Published on September 12, 2025

Blob videos are different from regular MP4 or MOV files. They’re usually served in small pieces over streaming protocols, making them less easy to download. That’s why “right-click and download” simply won’t work. To download you will need a Blob video downloader online.

In this article, we’ll talk about what blob videos are, why they’re difficult to download, and the easiest methods to download them online without installing bulky apps. We’ll cover browser extensions and even advanced tools like FliFlik UltConv Video Downloader, everything you need to download blob videos in high quality on any device.

Part 1: How to Find the Blob URL?

Downloading a blob video is not as simple as just right-clicking and copying the video link like regular videos. Instead of an .mp4 or .mov file, videos can be downloaded using a blob URL. Blob URLs are unique, temporary URLs generated by your browser that cannot be directly accessed. Here is how you can copy the blob URL before downloading.

▼ Detailed Steps to Find a Blob URL:

  • Step 1: Open the web page where you want to download the video.

  • Step 2: Click anywhere on the page and right-click to select ‘Inspect’. (You can also press Ctrl + Shift + I on Windows or Cmd + Option + I on Mac.)

  • find-blob-video-url-with-developer-tools
  • Step 3: When the DevTools panel appears, click the three vertical dots in the top-right corner and select Undock into a separate window (optional but recommended so it is easier to work with).

  • Step 4: Press Ctrl + F (Windows) or Cmd + F (Mac) in the DevTools panel to open the search bar.

  • Step 5: Type blob in the search field to search for blob URLs.

  • find-blob-video-url
  • Step 6: Go to the Network tab and type m3u8 in the filter (this is the extension of the video file that is often used with blob URLs).

  • Step 7: Click on the request. In the details panel, copy the Request URl.

notes Notes

you can’t copy this URL into the browser. It needs a software or tool to convert and download the video file

With the above steps, you can get URL for that video. But this is not always so easy. In fact, most of the time, you visit the page, right-click and select Inspect, just to grab the direct download URL. But instead of a regular URL, you get something like this: blob:https://example.com/. And you click it, but nothing happens and copying it into the browser leads you nowhere.

Why? Because blob URLs are not actual links to files, they are temporary, browser-generated pointers to streaming data. In order to see the actual source you have to use the Network tab in Developer Tools and capture the hidden m3u8 request behind the blob.
